HANS seamen, or CHARKOW, RUSSIA.

WATER-TUBE SEOTIONAL BOILER.

1 h c/ZZ whom-21 may concern Be it known that I, HANS BARLACH, a sub ject of the German Emperor, residing at Charkow, in the Empire of Russia, have in vented certain new and useful Improvemerits in VVater-Tube Sectional Boilers, of which the following is a full, clear, and exact description.

My invention refers to a water-tube sec-" tional boiler and is for the purpose of obtaining aver-y compact construction and at the same time. a large heating surface, aocompanied by great solidity and cheapness in the cost of manufacture. The arrange ment according to the invention is more particularly suitable for central 'heating,'but can, however, be used with advantage for other purposes;

The sectional boiler consists of tubular elements arranged beside eachother in verplanes, which elements, according to form with their outer portions, water-cooled throughout the whole surface, the jacketing of the boiler, and their inner portions form the walls of the feed chamber, fire box and smoke-fines and preferably also the grate. The elements are The openings for the gas and smoke are formed by constricting, bending or flattening the tubes or in some similar manner. The tubes will referably be of polygonal cross section, an the tubes'are so set together that more than the half of their surface can be utilized as heat- In order to increase the heating surface thetubes may be provided with ribs, the heightof which .will amount to 2% to 3 times the diameter of the tube.

I shall now describe my invention with.

reference to the. accompanying drawing in Figure 1 shows a cross section through a heating device according to the presentinvention and formed of two difierent shaped tubular elements.

Fig. 2 is a cross section through the device vertical to the plane of section according to Fig. 1'. Figs. 3 and4 are side views of both the tubular elements,

cf which the device according to Figs. 1 and '2. isooinposed. 5 'to ii showfurthr modifications .in cross section difiering esthe -fuel chamber h and drawing for this by the tubes f also situated I smoke fiues are Specification of Letters Patent.

sentiallyv by the means which are employed for forming the smoke openings. In the forms of construction according to Figs. 1 to 11 the tubes are of circular cross section.

Fig. 12 shows a further modification of the invention inwhich the tubes are of rectangular cross, section. Figs; 13* and 13 are Views in transverse section through coacting tubes of polygonal cross section suitable for construction of the tubular "elements. When using this cross section for the tubes a greater portion of the walls of the tube may be utilized as. heating surfaces than would be possible when using the circular cross section.

In the device according to Figs. 1 to 4 water flows from a lower water supply pipe 'a into the distributing pipe Z; of the tubular elements, which in its tutes the water grate. The cooling water flows from the distributing pipe 6 owing to the ascending power imparted to it by heating through the iacketing and branch pipes i f or 7 By setting together the tubular elements a smoke fines 2' are'formed.

The smoke fines are separated from the chamber by the tubes a, (Z' situated close.

beside each other. The passage of thesmok e 'from the fuel'chamber to the -flues is ren dered possible owing to the special .formation .of the pipes d, d

are not situated beside each other but an intermediate space is formed between the tubes (1 and ti.- As may be seen from the purpose the tubes (Z are bent at right angles whereas the tubes (1 are perfectly straight. The outer walls of the feed chamber are formed by the watertubes c situated quite close to each other and the'outer walls of the smoke flu'es are formed close to each other. In Fig. 5 the smoke also, formed by-bending the tubes d? at right angles whereas the tubes d are perfectly straight. Contrary to the forms of constructions shown in Figs. 1 to 4, however, arranged on both sides of the stove.

In Fig. 6 the tubes dtas well as the tubes first portion constie, f to the escape pipe 9.

v which has as result thatin their upper portion the tubes (Z, a?

openings are (Z are bent at an obtuse angle in their upper portion for. the purpose of forming [the openings for the smoke,

In Fig. 7 the tubes 6 bentat right angles have their outlet in the upper portion of'the tubes ,61 The tubes (F, d are also bent."

at right angles in their lower portion of the pipe 6; The smoke openings in this caseare Y formed by'arranging the horizontally running portions of the tubes CF, orjlof the tubes 6 staggered to each other.

Fig. 8 shows a boiler on the upper surface otwhich a cooking device is to be arranged. In order that the hot plate may be attacked directly by the fire the upper jacketing tubes are dispensed with. With the same object in view upper jacketing tubes might also be employed which are of less cross section than the-side jacketing tubes. The smoke openingsare formed in.

Fig. 8 as Well as in Fig. 9 in this thatless cross section is givento the tubes connecting the tubes d, e. p

In Fig. 10 the smoke openings are formed by constricting" the upper portion of the tube (Z In Fig. 11 the innen vertically rising tubes are dispensed with and are-substituted by horizontally running tubes 70. In this case the smoke openings are formed by dispensing with the upper horizontal tubes In Fig. 12, asabove mentioned, tubes of rectangular cross section are used for forming the tubular elements The smoke flues g are in this case formed by the ribs r of the tubes t and the smoke openingsby dispensing with the ribs of the tubes at the corresponding spots.

In Fig. 13*, various cross sections ottubes areshown! By usingthese cross sections for the tubes a relatively large heatin surface is obtained. The crosssections s own can be used with'any of the forms of construction shown in Fig. 1 to 11 and more particularly forthe jacketingtubes; They are so arranged that the flat portion of the upper surface, is situated outwards whereas the curved portion of the uppersurfaceis .face is presented to be acted upon by the gases than would be with the common ty of tube, and coiisequently the capacit of e boiler is increased accordingly. 'T e proportion oiL'the ribs in height are substantially two and one half to threetimes the div ameter of the tubes, inorder to obtain the most practical results.
